Yes there is a rubber ring that seals the bowl from the carb. But sounds like a couple of problems. You will prob need a complete rebuild kit, not hard, but a little time consuming. I recommend buying another carb, new or used, and putting that in there and then rebuilding the current one. Much quicker to swap the newly rebuilt than have to rebuild it when it goes bad and you need it.
Ever spit it out rather than swallow it?
Enjoy it while you can. One day you might be complaining about NOT getting random pop-ups in the morning.
